P h o t o n i c s a n d I n s t r u m e n t a t i o n 403 Email: [email protected] • Web: newport.com Electronic Fiber Cleavers FK11 The York Model FK11 Electronic Fiber Cleaver, enables every cleave substantially less than one degree. Operation is simple. A stripped fiber is placed in specially designed low torsion V-groove clamps. Constant axial tension is then applied to the fiber with the flip of a lever. Cleaving is initiated by releasing another lever. A precision ground diamond blade is attached to a resonant acoustic stepped horn. The ultrasonic horn resonance is maintained by an electronic circuit for the duration of the cleave and then automatically terminated to preserve battery life. The ultrasonically vibrating blade moves slowly toward the tensioned fiber on stictionless damped bearings. Cleaving then takes place without the damage from compressive stresses and blade intrusion into the fiber that is typical of conventional cleavers. The adjustable diamond blade normally gives 20,000 cleaves, and is replaceable. The patented anvil-less ultrasonic cleaving action minimizes fiber end contamination, hackle, and misting. This cleaving technique produces superb planar fiber ends of mirror quality. The York Model FK12 Angled Fiber Cleaver produces mirror-like fiber ends with cleave angles between 0° and 6–8°, to minimize back reflections. For many sensitive fiber optic systems back reflections can induce excessive noise and laser instability. Angle cleaving of fiber endfaces frustrates the backward propagation of endface reflections. The properly chosen cleave angle can reduce back reflections to less than -60 dB. The simple, fast and repeatable operation of the FK12 delivers convenience and performance unmatched by angle polishing or index matching schemes for reducing back reflections.
